[DRE-maint] Bug#569208: Found the real problem

[Lluís]

This bug is not in any ways related to bug #581383.

But in any case, I've just now found the root of the problem, that is not in any
ways related to redmine.

In fact, I had an old global alias defined by dokuwiki (in /etc/apache2/conf.d),
which prevented redmine users to access redmine's /wiki path.

Sorry for the inconvenience and thanks a lot for your time,
      Lluis
